You are playing a game in which you roll 2 dice. If the sum of the two numbers showing is greater than or equal to 10, you win. What is the probability that you win the first three times you play?

"Roll 2 dice, if the sum of the 2 numbers > or equal to 10 you win"

So the dices must be 

5 5 

5 6 

6 6 

6  4

4  6

That's 5 possibilities out of 30 I.e. 1/6 

But If you play first three times "I.e. rolling 2 dice 3 times"

you may get:

5 5 

6 6

5  4 etc.. 

3*6=18 possibilities, you could have any of the 5 possibilities above which you win

so 5/18
